Merge remote-tracking branch 'origin/imscope-docking' into integration_2024_w48 (!3030)

Imscope updates

- Using imgui docking branch - allows window docking.
- Moved scopes to different windows to allow docking.
- Disabled scatterplot for time domain samples - issues with amount of
  vertices caused segfaults.
- Disabled IQ heatmaps for RX IQ samples on gNB and UE - this was
  incorrect and currently I don't know how to fix it. This will be
  reenabled once it is.
- added a simple menu and disabled demo windows by default.
